I seem to recall taking this test when it was first making the rounds (before I had a blog, so I didn't record the results), and I think it said I was Picard. Marcus is a little closer (in the hair department, if nothing else), but still pretty far off.
An honest and chivalrous adventurer that pursues just causes, you would sacrifice much to help others.
I am a Ranger. We walk in the dark places no others will enter. We stand on the bridge and no-one may pass. We live for the One, we die for the One.
Ah... now, looking at the list of possible results, I note (as before) that it includes neither Michael Garibaldi nor Tom Bombadil... either of whom would (in one sense or another) be a much better match.
